WINDOW AND FLAP OPERATOR Filed Jan. 12. 1929 @WH/nwo Patented .lune 9, 1931v UNITED STATES noscoE G. wom), or PHOENIX, Anrzone WINDOW AND FLAI OPERATOR Application led Januaryl 12, 1929..'Seria1 No.V 332,124.

My invention relates to improvements in window and flap operators, and the The blades one (l) and two (2), of a suit? able size and material for strength and durability, are flat. y

Blade 1, wider than blade 2, curved at its upper dimension and straight at'its lower,

has suitable UShaped notches cut in its inner or concave edge to engage pin 7, of stlrrup receiver 4, when the window or flap is closed or opened to a desired position.

Blade v2, shaped similarly to blade 1, serves as a trip to disengage blade l, from engagement with pin 7 when grips 5 and G, are compressed together. To Jfurther insure complete engagement o blade 1, and pin 7 a flat curved spring 9, is placed inside stirrup receiver 4.

Blades or levers 1 and 2, each have at their upper curved extremities a suitable grip, made an intregal part of each, which enables them to be firmly and securely grasped when itis desired to open or` close a window or flap.

Pin 3, placed through blades 1 and 2 has three uses namely Y To hold the operator in place, to act as a hinge pin for the scissorlike motion of disengagement of blade 1, from pin 7, and to act as a pivot when the operator is swung from side to side in the openingand closing operations.

Pin 8, placed through stirrup receiver 4, near its point of attachmentpto a window serves as a check to receive the motion from blades l and 2, whenthe window or flap is opened.

Abutment pin 7 placed through the outer part of stirrup receiver 4, serves as a check for blade 2, while blade l, is disengaged and to receive the motion of blades l and 2, when the window or flap is closed and also asa stop Afor any notch in blade 1.

PATENT (OFFICE Pff VIn the manner of operation the grips 5 and l 6, are grasped and compressed which by means or' pin 3 produces a scissorelike motion forcing blade 2, forward against pin 7 and blade l, backward thus disengaging any 1 notch from pin 7, thenby a motion of the grips 5 and 6, right or let or'windows, up v or down :tor flaps, the window or flap is opened or closed.

I believe that my invention is novel in every respect and I know of no operator so used and assembledor using Vthis principle of operation. I claim 4l. An operator for a hingedwindow com vprising a guide for attachment to the window, said guide having an abutment, "a lever slidably engaged with said guide and having means to engage said abutment to hold theV lever normally against sliding with respect to the guide, a ulcrum for said lever adapted for mountingon the window frame-and a second lever Jfulcrumed at one side of the first named lever, the two levers being provided with hand grip portions adapted to be moved 'toward each other to move said levers in scissors-like manner, said second lever being movement of the first named lever from' en-r Y gagement with said abutment;

2. An operator for a hinged window comprising a guide for 'attachmentto' the window, said guide having an abutment, a lever slidably engaged with said guide and having means to engage said abutment to'hold the Y lever normally against sliding'with respect to the guide, a fulcrum for'said leveradapted for mounting on the window frame, and a second lever slidably engaged with said guide and Yfulcrumed at one side of the rst named lever, theV two levers being provided with hand grip portions adapted to be moved toward each other to move said levers in scissors-like manner, said'second lever being adapted upon such movement to thrust against Va portion o-sad guide and cause V-movement of the first named lever from engagement with said abutment.

3. A structure as specified in claim 2; said second lever vbeing fulorumed on said fulorum ofthe first named lever.

, 4. An operator for a hinged Window eom- Y l prising a guide for attachment to the 'vvn-V dow, said guide having an abutment, varlever slidably engaged With said Iguide and havn ing means to engage said .abutment to hold the lever normally against sliding., with respect tothe guide, a :Fulcrum forsaid lever adapted formountng on the Window frame,

and a second lever ulorumed at o ne side ofV the first named leverythe two leversbeng adapted for movement n scissors-like manner, saidr second leverheing adapted upon such movement to thrust againstra portion of saidguide and Cause movement of therstnamed lever from engagement with said abutment.
